Brief Summary:
The effectiveness of an optimized extinction training is investigated in spider-fearful individuals. Participants will undergo a one-session standardized extinction training, either with or without occasional metal imagination of most feared apprehension towards spiders. The effectiveness of the training is measured by symptom improvement according to subjective ratings and behavioural avoidance tests one week later.
Detailed Description:
The present study aims to investigate the applicability of an optimized exposure training using imagination. Exposure training is an effective approach to the treatment of various anxiety disorders. However, there are a significant number of patients who do not benefit or who develop anxiety following successful treatment. The process of extinction underlying exposure is the focus of current research on optimizing exposure. In this regard, one promising approach for improving extinction learning involves the occasional presentation of fear-generating stimuli (unconditioned stimuli \[US\]; often an electrical stimulus in experimental studies) during extinction (occasional reinforced extinction, ORE). Previous experimental studies provide preliminary evidence for a less pronounced return of fear after extinction training with occasional presentation of the US. In clinical practice, this strategy is recommended to optimize extinction learning in the treatment of individuals with anxiety. However, the transfer of the procedure used (real presentation of an unconditioned stimulus) into clinical practice seems difficult to realize. One way to facilitate the transfer of the ORE approach into clinical practice could be the use of vivid imagination of a personally relevant fear-generating situation during extinction training/exposure (e.g., patients' central concerns). Therefore, the aim of the present study is to examine the applicability of ORE using imagination. In this context, a standardized extinction training either with or without mental imagination of a personally relevant fear situation (e.g., central concern of the consequences when confronted with spiders) will be performed in individuals with spider-fearful individuals. The approach used for individuals with spider fear is well established and has been successfully implemented in previous studies by instructed trainers (e.g., individuals with a bachelor's degree in psychology). The aim of this randomized controlled trial in healthy individuals with increased fear of spiders is to investigate whether optimized extinction training (extinction training + imagination) is more effective in reducing fear of spiders in the long term compared to standard extinction training.
